If a credit card is already added to a PayPal account then it won't let you use that card to process directly with Payments Advanced. The system expects buyers to login to PayPal and just choose that credit card as their funding source if they want to pay with it.

As for testing on the sandbox, I've always used old, expired credit cards I have laying around and they seem to work fine for me.

You could always try the ones starting on page 87 of the PayFlow documentation, too. They should work.

Get the content of the JSON file using file_get_contents():

$str = file_get_contents('http://example.com/example.json/');

Now decode the JSON using json_decode():

$json = json_decode($str, true); // decode the JSON into an associative array

You have an associative array containing all the information. To figure out how to access the values you need, you can do the following:

echo '<pre>' . print_r($json, true) . '</pre>';

This will print out the contents of the array in a nice readable format. Note that the second parameter is set to true in order to let print_r() know that the output should be returned (rather than just printed to screen). Then, you access the elements you want, like so:

$temperatureMin = $json['daily']['data'][0]['temperatureMin'];
$temperatureMax = $json['daily']['data'][0]['temperatureMax'];

Or loop through the array however you wish:

foreach ($json['daily']['data'] as $field => $value) {
    // Use $field and $value here
}

Demo!

Suppose we want to run your Django web server (in Linux) that there is space between your path (path='/home/<you>/<first-path-section> <second-path-section>'), so do the following:

import subprocess

args = ['{}/manage.py'.format('/home/<you>/<first-path-section> <second-path-section>'), 'runserver']
res = subprocess.Popen(args, stdout=subprocess.PIPE)
output, error_ = res.communicate()

if not error_:
    print(output)
else:
    print(error_)

[Note]:

• Do not forget accessing permission: chmod 755 -R <'yor path'>
• manage.py is exceutable: chmod +x manage.py

I just came across this problem when I replaced a failing disk. I had copied over the system files to the new disk, and was good about replacing the old disk's UUID entry with the new disk's UUID in fstab.

However I had not replaced the UUID in the grub.conf (sometimes menu.lst) file in /boot/grub. So check your grub.conf file, and if the "kernel" line has something like

kernel ... root=UUID=906eaa97-f66a-4d39-a39d-5091c7095987 

it likely has the old disk's UUID. Replace it with the new disk's UUID and run grub-install (if you're in a live CD rescue you may need to chroot or specify the grub directory).

See this:

In the Microsoft .NET framework, an assembly is a partially compiled code library for use in deployment, versioning and security

document.getElementById('myDiv').style.height = 500;

This is the very basic JS code required to adjust the height of your object dynamically. I just did this very thing where I had some auto height property, but when I add some content via XMLHttpRequest I needed to resize my parent div and this offsetheight property did the trick in IE6/7 and FF3

function fixNumericScrolling() {
$$( "input[type=number]" ).addEvent( "mousewheel", function(e) {
    stopAll(e);     
} );
}

function stopAll(e) {
if( typeof( e.preventDefault               ) != "undefined" ) e.preventDefault();
if( typeof( e.stopImmediatePropagation     ) != "undefined" ) e.stopImmediatePropagation();
if( typeof( event ) != "undefined" ) {
    if( typeof( event.preventDefault           ) != "undefined" ) event.preventDefault();
    if( typeof( event.stopImmediatePropagation ) != "undefined" ) event.stopImmediatePropagation();
}

return false;
}

Integrated application pool mode

When an application pool is in Integrated mode, you can take advantage of the integrated request-processing architecture of IIS and ASP.NET. When a worker process in an application pool receives a request, the request passes through an ordered list of events. Each event calls the necessary native and managed modules to process portions of the request and to generate the response.

There are several benefits to running application pools in Integrated mode. First the request-processing models of IIS and ASP.NET are integrated into a unified process model. This model eliminates steps that were previously duplicated in IIS and ASP.NET, such as authentication. Additionally, Integrated mode enables the availability of managed features to all content types.

Classic application pool mode

When an application pool is in Classic mode, IIS 7.0 handles requests as in IIS 6.0 worker process isolation mode. ASP.NET requests first go through native processing steps in IIS and are then routed to Aspnet_isapi.dll for processing of managed code in the managed runtime. Finally, the request is routed back through IIS to send the response.

This separation of the IIS and ASP.NET request-processing models results in duplication of some processing steps, such as authentication and authorization. Additionally, managed code features, such as forms authentication, are only available to ASP.NET applications or applications for which you have script mapped all requests to be handled by aspnet_isapi.dll.

Be sure to test your existing applications for compatibility in Integrated mode before upgrading a production environment to IIS 7.0 and assigning applications to application pools in Integrated mode. You should only add an application to an application pool in Classic mode if the application fails to work in Integrated mode. For example, your application might rely on an authentication token passed from IIS to the managed runtime, and, due to the new architecture in IIS 7.0, the process breaks your application.

I guess you're learning how to Python. The other answers are right. But I am going to answer your main question: "how to calculate percentage in python"

Although it works the way you did it, it doesn´t look very pythonic. Also, what happens if you need to add a new subject? You'll have to add another variable, use another input, etc. I guess you want the average of all marks, so you will also have to modify the count of the subjects everytime you add a new one! Seems a mess...

I´ll throw a piece of code where the only thing you'll have to do is to add the name of the new subject in a list. If you try to understand this simple piece of code, your Python coding skills will experiment a little bump.

#!/usr/local/bin/python2.7

marks = {} #a dictionary, it's a list of (key : value) pairs (eg. "Maths" : 34)
subjects = ["Tamil","English","Maths","Science","Social"] # this is a list

#here we populate the dictionary with the marks for every subject
for subject in subjects:
   marks[subject] = input("Enter the " + subject + " marks: ")

#and finally the calculation of the total and the average
total = sum(marks.itervalues())
average = float(total) / len(marks)

print ("The total is " + str(total) + " and the average is " + str(average))

Here you can test the code and experiment with it.

It is bounded on the lower end by 2^(n/2) and on the upper end by 2^n (as noted in other comments). And an interesting fact of that recursive implementation is that it has a tight asymptotic bound of Fib(n) itself. These facts can be summarized:

T(n) = O(2^(n/2))  (lower bound)
T(n) = O(2^n)   (upper bound)
T(n) = T(Fib(n)) (tight bound)

The tight bound can be reduced further using its closed form if you like.

You can use:

window.location.href = '/Branch/Details/' + id;

But your Ajax code is incomplete without success or error functions.

The following is works best in my opinion:

Get-Item Env:PATH

1. It's shorter and therefore a little bit easier to remember than Get-ChildItem. There's no hierarchy with environment variables.
2. The command is symmetrical to one of the ways that's used for setting environment variables with Powershell. (EX: Set-Item -Path env:SomeVariable -Value "Some Value")
3. If you get in the habit of doing it this way you'll remember how to list all Environment variables; simply omit the entry portion. (EX: Get-Item Env:)

I found the syntax odd at first, but things started making more sense after I understood the notion of Providers. Essentially PowerShell let's you navigate disparate components of the system in a way that's analogous to a file system.

What's the point of the trailing colon in Env:? Try listing all of the "drives" available through Providers like this:

PS> Get-PSDrive

I only see a few results... (Alias, C, Cert, D, Env, Function, HKCU, HKLM, Variable, WSMan). It becomes obvious that Env is simply another "drive" and the colon is a familiar syntax to anyone who's worked in Windows.

You can navigate the drives and pick out specific values:

Get-ChildItem C:\Windows
Get-Item C:
Get-Item Env:
Get-Item HKLM:
Get-ChildItem HKLM:SYSTEM

• Sample, in MyRecyclerViewAdapter, add method:

  public interface ItemClickListener {
     void onItemClick(View view, int position);
  }
  

• In MainActivity.java

  @Override
  public void onItemClick(View view, int position) {
  Context context=view.getContext();
  Intent intent=new Intent();
  switch (position){
      case 0:
          intent =  new Intent(context, ChildActivity.class);
          context.startActivity(intent);
          break;
     }
  }
  

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>

            </div>
          </div>
        </div>

      </form>
    </div>

I hope this helps someone. Thank you.

Memory debugging tools are worth their weight in gold but over the years I've found that two simple ideas can be used to prevent most memory/resource leaks from being coded in the first place.

1. Write release code immediatly after writing the acquisition code for the resources you want to allocate. With this method its harder to "forget" and in some sense forces one to seriously think of the lifecycle of resources being used upfront instead of as an aside.

2. Use return as sparringly as possible. What is allocated should only be freed in one place if possible. The conditional path between acquisition of resource and release should be designed to be as simple and obvious as possible.

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

public function getSalary()
    {
        $this->db->select('tbl_salary.*,tbl_employee.empFirstName');
        $this->db->from('tbl_salary');
        $this->db->join('tbl_employee','tbl_employee.empID = strong texttbl_salary.salEmpID');
        $this->db->where('tbl_salary.status',0);
        $query = $this->db->get();
        return $query->result();
    }

shuffle(names) is an in-place operation. Drop the assignment.

This function returns None and that's why you have the error:

TypeError: object of type 'NoneType' has no len()

You can use

<div class="col-sm-12" *ngIf="event.attendees?.length">

Without event.attendees?.length > 0 or even event.attendees?length != 0

Because ?.length already return boolean value.

If in array will be something it will display it else not.

I have to offer this as a better approach - you don't always have the luxury of an identity field:

UPDATE m
SET [status]=10
FROM (
  Select TOP (10) *
  FROM messages
  WHERE [status]=0
  ORDER BY [priority] DESC
) m

You can also make the sub-query as complicated as you want - joining multiple tables, etc...

Why is this better? It does not rely on the presence of an identity field (or any other unique column) in the messages table. It can be used to update the top N rows from any table, even if that table has no unique key at all.

Three related packages for covering this issue with many advanced options are:

• sliding_up_panel
• modal_bottom_sheet
• sliding_panel

You can find the OS name and version in the navigator object, as others have answered. The standard, cross-browser place to find this information is in the navigator.userAgent property. However, user agent strings vary widely by OS and browser.

So, I created a script to encapsulate this logic and report on the most common OSes and browsers in a familiar way, like http://www.whatsmybrowser.org.

I open-sourced the script and uploaded it to github, https://github.com/keithws/browser-report. Pull requests are welcome!

From the title I'm guessing you only need one result per unique row? If this is the case, take a look at the GROUP BY clause (or SELECT DISTINCT).

You could try

httpResponseMessage.Content.Headers.Add("Content-Type", "application/octet-stream");

I had the same issue while using vagrant. So from my Mac I was trying to ssh to a vagrant box (CentOS 7)

Solved it by amending the /etc/ssh/sshd_config PasswordAuthentication yes then re-started the service using sudo systemctl restart sshd

Hope this helps.

Set up a batch file which you can invoke. Pass the path the batch file, and have the batch file set the environment variable and then invoke NUnit.

Together they will help you built awesome scrappers mapping directly HTML to POJOs and bypassing any classical scrapping problems in only a matter of minutes!

Hope this might help some people here!

Disclaimer, I am the one who developed it, feel free to let me know your remarks!

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:

param(
    [Parameter(Position = 0)]
    [string[]]$Hosts,
    [string]$VLAN
    )

foreach ($i in $Hosts)  
{ 
    Do-Stuff $i
}

Then call it like:

.\script.ps1 host1, host2, host3 -VLAN 2

Notice the comma between the values. This collects them in an array

Using window functions (works in Oracle, Postgres 8.4, SQL Server 2005, DB2, Sybase, Firebird 3.0, MariaDB 10.3)

select * from (
    select
        username,
        date,
        value,
        row_number() over(partition by username order by date desc) as rn
    from
        yourtable
) t
where t.rn = 1

There are numerous caveats in the javadoc for the toFront() method which may be causing your problem.

But I'll take a guess anyway, when "only the tab in the taskbar flashes", has the application been minimized? If so the following line from the javadoc may apply:

"If this Window is visible, brings this Window to the front and may make it the focused Window."

For call from dialer (No permission needed):

   fun callFromDailer(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_DIAL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

For direct call from app(Permission needed):

  fun callDirect(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_CALL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: SecurityException) {
            Toast.makeText(mContext, "Need call permission", Toast.LENGTH_LONG).show()
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

Permission:

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

Note that you could as well plot directly from ce (after the comma removing) using the column name :

hist(ce$Weight)

(As opposed to using hist(ce[1]), which would lead to the same "must be numeric" error.)

This also works for a database query result.

You need to enable SSL in your PHP config. Load up php.ini and find a line with the following:

;extension=php_openssl.dll

Uncomment it. :D

(by removing the semicolon from the statement)

extension=php_openssl.dll

As of July 2018, Pypi now requires that clients connecting to it use TLS 1.2. This is an issue if you're using the version of python shipped with MacOS (2.7.10) because it only supports TLS 1.0. You can change the version of ssl that python is using to fix the problem or upgrade to a newer version of python. Use homebrew to install the new version of python outside of the default library location.

brew install python@2

You can try this code. This is Simple PHP Image Deleting code from the server.

<form method="post">
<input type="text" name="photoname"> // You can type your image name here...
<input type="submit" name="submit" value="Delete">
</form>

<?php
if (isset($_POST['submit'])) 
{
$photoname = $_POST['photoname'];
if (!unlink($photoname))
  {
  echo ("Error deleting $photoname");
  }
else
  {
  echo ("Deleted $photoname");
  }
}
?>

Both getSingleResult() and getOneOrNullResult() will throw an exception if there is more than one result. To fix this problem you could add setMaxResults(1) to your query builder.

 $firstSubscriber = $entity->createQueryBuilder()->select('sub')
        ->from("\Application\Entity\Subscriber", 'sub')
        ->where('sub.subscribe=:isSubscribe')
        ->setParameter('isSubscribe', 1)  
        ->setMaxResults(1)
        ->getQuery()
        ->getOneOrNullResult();

Before you try searching for the elements within the iframe you will have to switch Selenium focus to the iframe.

Try this before searching for the elements within the iframe:

driver.switchTo().frame(driver.findElement(By.name("iFrameTitle")));

$(this.parentNode).addClass('newClass');

I stumbled across this too and the solution was unironically to simply run this:

$eval and $parse don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.

Q: What exactly is $eval doing? Why does it need its own mini parsing language?

From the docs:

Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.

It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).

Q: Why isn't plain old javascript "eval" being used?

Because it's not actually evaluating JavaScript. As the docs say:

If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.

The docs linked to above have a lot more information.

str = "255.255.255.255"
print(str.split('.'))

list1 = str.split('.')

condition=0

if len(list1)==4:
    for i in list1:
        if int(i)>=0 and int(i)<=255:
            condition=condition+1

if condition!=4:
    print("Given number is not IP address")
else:
    print("Given number is valid IP address")

I would like to add a bit more to MadProgrammer's Answer.

In case of multiple line writing, when executing the command

writer.write(string);

one may notice that the newline characters are omitted or skipped in the written file even though they appear during debugging or if the same text is printed onto the terminal with,

System.out.println("\n");

Thus, the whole text comes as one big chunk of text which is undesirable in most cases. The newline character can be dependent on the platform, so it is better to get this character from the java system properties using

String newline = System.getProperty("line.separator");

and then using the newline variable instead of "\n". This will get the output in the way you want it.

You can add a tree observer to the layout. This should return the correct width and height. onCreate() is called before the layout of the child views are done. So the width and height is not calculated yet. To get the height and width, put this on the onCreate() method:

    final LinearLayout layout = (LinearLayout) findViewById(R.id.YOUR_VIEW_ID);
    ViewTreeObserver vto = layout.getViewTreeObserver(); 
    vto.addOnGlobalLayoutListener (new OnGlobalLayoutListener() { 
        @Override 
        public void onGlobalLayout() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                    layout.getViewTreeObserver()
                            .removeOnGlobalLayoutListener(this);
                } else {
                    layout.getViewTreeObserver()
                            .removeGlobalOnLayoutListener(this);
                }
            int width  = layout.getMeasuredWidth();
            int height = layout.getMeasuredHeight(); 

        } 
    });

$destroy can refer to 2 things: method and event

1. method - $scope.$destroy

.directive("colorTag", function(){
  return {
    restrict: "A",
    scope: {
      value: "=colorTag"
    },
    link: function (scope, element, attrs) {
      var colors = new App.Colors();
      element.css("background-color", stringToColor(scope.value));
      element.css("color", contrastColor(scope.value));

      // Destroy scope, because it's no longer needed.
      scope.$destroy();
    }
  };
})

2. event - $scope.$on("$destroy")

See @SunnyShah's answer.

I found the following article to be very helpful:

https://weblog.west-wind.com/posts/2015/Apr/29/Adding-minimal-OWIN-Identity-Authentication-to-an-Existing-ASPNET-MVC-Application#MinimalCodeSummary

In my case, I had to set the following before Owin authentication would work instead of windows authentication:

<system.web>   
    <authentication mode="None" />   
<system.web>

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, it can tell if one of the Runnables passed along by the Choreographer.post* apis doesn't finish in one frame's time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message "The application may be doing too much work on its main thread." could be misleading.

Update: Sep-2018

You can use URLSearchParams which is simple and has decent (but not complete) browser support.

const urlParams = new URLSearchParams(window.location.search);
const myParam = urlParams.get('myParam');

Original

You don't need jQuery for that purpose. You can use just some pure JavaScript:

function getParameterByName(name, url = window.location.href) {
    name = name.replace(/[\[\]]/g, '\\$&');
    var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, ' '));
}

Usage:

// query string: ?foo=lorem&bar=&baz
var foo = getParameterByName('foo'); // "lorem"
var bar = getParameterByName('bar'); // "" (present with empty value)
var baz = getParameterByName('baz'); // "" (present with no value)
var qux = getParameterByName('qux'); // null (absent)

NOTE: If a parameter is present several times (?foo=lorem&foo=ipsum), you will get the first value (lorem). There is no standard about this and usages vary, see for example this question: Authoritative position of duplicate HTTP GET query keys.

NOTE: The function is case-sensitive. If you prefer case-insensitive parameter name, add 'i' modifier to RegExp

This is an update based on the new URLSearchParams specs to achieve the same result more succinctly. See answer titled "URLSearchParams" below.

 <RichTextBox>
     <FlowDocument PageHeight="180">
         <Paragraph>
             <Run Text="{Binding Text, Mode=TwoWay}"/>
          </Paragraph>
     </FlowDocument>
 </RichTextBox>

This seems to be the easiest way by far and isn't displayed in any of these answers.

In the view model just have the Text variable.

If you only need to find a free port for later use, here is a snippet similar to a previous answer, but shorter, using socketserver:

import socketserver

with socketserver.TCPServer(("localhost", 0), None) as s:
    free_port = s.server_address[1]

Note that the port is not guaranteed to remain free, so you may need to put this snippet and the code using it in a loop.

For strings starting with integers, e.g., @"123", @"456 ft", @"7.89", etc., use -[NSString integerValue].

So, @([@"12.8 lbs" integerValue]) is like doing [NSNumber numberWithInteger:12].

There's already a question about this, you could perhaps read it

Deep cloning objects

There's no Clone() method as it exists in Java for example, but you could include a copy constructor in your clases, that's another good approach.

class A
{
  private int attr

  public int Attr
  {
     get { return attr; }
     set { attr = value }
  }

  public A()
  {
  }

  public A(A p)
  {
     this.attr = p.Attr;
  }  
}

This would be an example, copying the member 'Attr' when building the new object.

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

if you replace in the function SimpleDateFormat("hh") with ("HH") will format the hour in 24 hours instead of 12.

SimpleDateFormat df = new SimpleDateFormat("HH:mm");

I have a very well working solution for tables of max-width: 100%. Just use word-break: break-all; for the table cells (except heading cells) to break all long text into several lines:

<!DOCTYPE html>
<html>
<head>
<style>

table {
  max-width: 100%; 
}
table td {
  word-break: break-all;
}

</style>
</head>
<body>

<table border="1">
  <tr>
    <th><strong>Input</strong></th>
    <th><strong>Output</strong></th>
  </tr>
  <tr>
    <td>some text</td>
    <td>12b6459fc6b4cabb4b1990be1a78e4dc5fa79c3a0fe9aa9f0386d673cfb762171a4aaa363b8dac4c33e0ad23e4830888</td>
  </tr>
</table>

</body>
</html>

This will render like this (when the screen width is limited):

It looks like you are willing to create a temporary Map, so I'd do it like this:

Map tmp = new HashMap(patch);
tmp.keySet().removeAll(target.keySet());
target.putAll(tmp);

Here, patch is the map that you are adding to the target map.

Thanks to Louis Wasserman, here's a version that takes advantage of the new methods in Java 8:

patch.forEach(target::putIfAbsent);

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

• this is a merge of both ClandestineCoder & Binh WPO.

the problem with the script tag arrows is that they can have more than one variant

ex. (< = < = <) & ( > = > = >)

so instead of creating a pattern array with like a bazillion variant, imho a better solution would be

return preg_replace('/script.*?\/script/ius', '', $text)
       ? preg_replace('/script.*?\/script/ius', '', $text)
       : $text;

this will remove anything that look like script.../script regardless of the arrow code/variant and u can test it in here https://regex101.com/r/lK6vS8/1

java.util.Formatter will do left and right padding. No need for odd third party dependencies (would you want to add them for something so trivial).

[I've left out the details and made this post 'community wiki' as it is not something I have a need for.]

You (and KMulligan) are misunderstanding _ViewStart pages.

_ViewStart will always execute, before your page starts.
It is intended to be used to initialize properties (such as Layout); it generally should not contain markup. (Since there is no way to override it).

The correct pattern is to make a separate layout page which calls RenderBody, and set the Layout property to point to this page in _ViewStart.

You can then change Layout in your content pages, and the changes will take effect.

You could use preg_split instead of explode and split on [ ]+ (one or more spaces). But I think in this case you could go with preg_match_all and capturing:

preg_match_all('/[ ]php[ ]+\S+[ ]+(\S+)/', $input, $matches);
$result = $matches[1];

The pattern matches a space, php, more spaces, a string of non-spaces (the path), more spaces, and then captures the next string of non-spaces. The first space is mostly to ensure that you don't match php as part of a user name but really only as a command.

An alternative to capturing is the "keep" feature of PCRE. If you use \K in the pattern, everything before it is discarded in the match:

preg_match_all('/[ ]php[ ]+\S+[ ]+\K\S+/', $input, $matches);
$result = $matches[0];

I would use preg_match(). I do something similar for many of my system management scripts. Here is an example:

$test = "user     12052  0.2  0.1 137184 13056 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust1 cron
user     12054  0.2  0.1 137184 13064 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust3 cron
user     12055  0.6  0.1 137844 14220 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust4 cron
user     12057  0.2  0.1 137184 13052 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust89 cron
user     12058  0.2  0.1 137184 13052 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust435 cron
user     12059  0.3  0.1 135112 13000 ?        Ss   10:00   0:00 php /home/user/public_html/utilities/runProcFile.php cust16 cron
root     12068  0.0  0.0 106088  1164 pts/1    S+   10:00   0:00 sh -c ps aux | grep utilities > /home/user/public_html/logs/dashboard/currentlyPosting.txt
root     12070  0.0  0.0 103240   828 pts/1    R+   10:00   0:00 grep utilities";

$lines = explode("\n", $test);

foreach($lines as $line){
        if(preg_match("/.php[\s+](cust[\d]+)[\s+]cron/i", $line, $matches)){
                print_r($matches);
        }

}

The above prints:

Array
(
    [0] => .php cust1 cron
    [1] => cust1
)
Array
(
    [0] => .php cust3 cron
    [1] => cust3
)
Array
(
    [0] => .php cust4 cron
    [1] => cust4
)
Array
(
    [0] => .php cust89 cron
    [1] => cust89
)
Array
(
    [0] => .php cust435 cron
    [1] => cust435
)
Array
(
    [0] => .php cust16 cron
    [1] => cust16
)

You can set $test to equal the output from exec. the values you are looking for would be in the if statement under the foreach. $matches[1] will have the custx value.

Should this not work?

If your device knows the Wifi configs (already stored), we can bypass rocket science. Just loop through the configs an check if the SSID is matching. If so, connect and return.

Set permissions:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

Connect:

    try {
    String ssid = null;
    if (wifi == Wifi.PCAN_WIRELESS_GATEWAY) {
        ssid = AesPrefs.get(AesConst.PCAN_WIRELESS_SSID,
                context.getString(R.string.pcan_wireless_ssid_default));
    } else if (wifi == Wifi.KJ_WIFI) {
        ssid = context.getString(R.string.remote_wifi_ssid_default);
    }

    WifiManager wifiManager = (WifiManager) context.getApplicationContext()
            .getSystemService(Context.WIFI_SERVICE);

    List<WifiConfiguration> wifiConfigurations = wifiManager.getConfiguredNetworks();

    for (WifiConfiguration wifiConfiguration : wifiConfigurations) {
        if (wifiConfiguration.SSID.equals("\"" + ssid + "\"")) {
            wifiManager.enableNetwork(wifiConfiguration.networkId, true);
            Log.i(TAG, "connectToWifi: will enable " + wifiConfiguration.SSID);
            wifiManager.reconnect();
            return null; // return! (sometimes logcat showed me network-entries twice,
            // which may will end in bugs)
        }
    }
} catch (NullPointerException | IllegalStateException e) {
    Log.e(TAG, "connectToWifi: Missing network configuration.");
}
return null;

Assuming that EXIT_CODE is referring to System . exit ( exit_code ) then you could do

enum ExitCode
{
      NORMAL_SHUTDOWN ( 0 ) , EMERGENCY_SHUTDOWN ( 10 ) , OUT_OF_MEMORY ( 20 ) , WHATEVER ( 30 ) ;

      private int value ;

      ExitCode ( int value )
      {
           this . value = value ;
      }

      public void exit ( )
      {
            System . exit ( value ) ;
      }
}

Then you can put the following at appropriate spots in your code

ExitCode . NORMAL_SHUTDOWN . exit ( ) '

• Get the public key from the client phone (adb host)

  cat /data/.android/adbkey.pub

• copy the above public key to the target phone's /data/misc/adb/adb_keys location. (you may need to stop the adb daemon first with stop adbd)

  cat /data/misc/adb/adb_keys

verify both cat outputs match.

try restarting adb daemon on target start adbd or just reboot them.

If you are having problems reading or writing to ADB KEYS in above steps, try setting environment variable ADB_KEYS_PATH with a temporary path (eg: /data/local/tmp). Refer to that link it goes into more details

    "On the host, the user public/private key pair is automatically generated,
    if it does not exist, when the adb daemon starts and is stored in
    $HOME/.android/adb_key(.pub) or in $ANDROID_SDK_HOME on windows. If needed,
    the ADB_KEYS_PATH env variable may be set to a :-separated (; under
    Windows) list of private keys, e.g. company-wide or vendor keys.

    On the device, vendors public keys are installed at build time in
    /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys"

Add attribute as:

$('#Selector_id').attr('disabled',true);

Open your Android SDK Manager and ensure that you download/install a system image for the API level you are developing with.

Here's a short PowerShell script to do what you probably expect:

$sourceNugetExe = "https://dist.nuget.org/win-x86-commandline/latest/nuget.exe"
$targetNugetExe = "$rootPath\nuget.exe"
Invoke-WebRequest $sourceNugetExe -OutFile $targetNugetExe
Set-Alias nuget $targetNugetExe -Scope Global -Verbose

Note that Invoke-WebRequest cmdlet arrived with PowerShell v3.0. This article gives the idea.

In the old console layout :

• Select your project
• Select menu item "API access"
• Go to the section below "Create another client ID", called "Simple API Access"
• Choose one of the following options, depending on what kind of app you're creating (server side languages should use the first option - JS should use the second) :
  • Key for server apps (with IP locking)
  • Key for browser apps (with referers)

In the new cloud console layout :

• Select your project
• Choose menu item "APIs & auth"
• Choose menu item "Registered app"
• Register an app of type "web application"
• Choose one of the following options, depending on what kind of app you're creating (server side languages should use the first option - JS should use the second) :
  • Key for server apps (with IP locking)
  • Key for browser apps (with referers)

In case of both procedures, you find your client ID and client secret at the same page. If you're using a different client ID and client secret, replace it with the ones you find here.

During my first experiments today, I've succesfully used the "Key for server apps" as a developer key for connecting with the "contacts", "userinfo" and "analytics" API. I did this using the PHP client.

Wading through the Google API docs certainly is a pain in the @$$... I hope this info will be useful to anyone.

To hide scroll bars for elements with overflowing content use.

.div{

  scrollbar-width: none; /* The most elegant way for Firefox */

}    

In case you want to deeply iterate into a complex (nested) object for each key & value, you can do so using Object.keys():

const iterate = (obj) => {
    Object.keys(obj).forEach(key => {

    console.log(`key: ${key}, value: ${obj[key]}`)

    if (typeof obj[key] === 'object') {
            iterate(obj[key])
        }
    })
}

Try Facetype.js, you convert your .TTF font into a Javascript file. Full SEO compatible, supports FF, IE6 and Safari and degrades gracefully on other browsers.

For those errors where modelstate.isvalid is false, I generally send the error as it is thrown by the code. Its easy to understand for the developer who is consuming my service. I generally send the result using below code.

     if(!ModelState.IsValid) {
                List<string> errorlist=new List<string>();
                foreach (var value in ModelState.Values)
                {
                    foreach(var error in value.Errors)
                    errorlist.Add( error.Exception.ToString());
                    //errorlist.Add(value.Errors);
                }
                HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.BadRequest,errorlist);}

This sends the error to the client in below format which is basically a list of errors:

    [

Assuming you already know lists are of equal size, the following will guarantee True if and only if two vectors are exactly the same (including order)

functools.reduce(lambda b1,b2: b1 and b2, map(lambda e1,e2: e1==e2, listA, ListB), True)

Example:

>>> from functools import reduce
>>> def compvecs(a,b):
...     return reduce(lambda b1,b2: b1 and b2, map(lambda e1,e2: e1==e2, a, b), True)
... 
>>> compvecs(a=[1,2,3,4], b=[1,2,4,3])
False
>>> compvecs(a=[1,2,3,4], b=[1,2,3,4])
True
>>> compvecs(a=[1,2,3,4], b=[1,2,4,3])
False
>>> compare_vectors(a=[1,2,3,4], b=[1,2,2,4])
False
>>>

You cannot treat == or || as chars, since they are not chars, but a sequence of chars.

You could make your switch...case work on strings instead.

You can run the script with python -m from the relevant root dir. And pass the "modules path" as argument.

Example: $ python -m module.sub_module.main # Notice there is no '.py' at the end.

Another example:

$ tree  # Given this file structure
.
+-- bar
¦   +-- __init__.py
¦   +-- mod.py
+-- foo
    +-- __init__.py
    +-- main.py

$ cat foo/main.py
from bar.mod import print1
print1()

$ cat bar/mod.py
def print1():
    print('In bar/mod.py')

$ python foo/main.py  # This gives an error
Traceback (most recent call last):
  File "foo/main.py", line 1, in <module>
    from bar.mod import print1
ImportError: No module named bar.mod

$ python -m foo.main  # But this succeeds
In bar/mod.py

This seems to be what you're looking for:

g <- ggplot(x, aes(reorder(variable, value), value))
g + geom_bar() + scale_y_continuous(formatter="percent") + coord_flip()

The reorder() function will reorder your x axis items according to the value of variable.

In SQL Server Enterprise Manager, open \Server Objects\Linked Servers\Providers, right click on the OraOLEDB.Oracle provider, select properties and check the "Allow inprocess" option. Recreate your linked server and test again.

You can also execute the following query if you don't have access to SQL Server Management Studio :

EXEC master.dbo.sp_MSset_oledb_prop N'OraOLEDB.Oracle', N'AllowInProcess', 1

Just to contribute,

there is a linecache module in python, here is two links that can help.

linecache module documentation
linecache source code

In a sense, you can "dump" a whole file into its cache , and read it with linecache.cache data from class.

import linecache as allLines
## have in mind that fileName in linecache behaves as any other open statement, you will need a path to a file if file is not in the same directory as script
linesList = allLines.updatechache( fileName ,None)
for i,x in enumerate(lineslist): print(i,x) #prints the line number and content
#or for more info
print(line.cache)
#or you need a specific line
specLine = allLines.getline(fileName,numbOfLine)
#returns a textual line from that number of line

For additional info, for error handling, you can simply use

from sys import exc_info
try:
     raise YourError # or some other error
except Exception:
     print(exc_info() )

I have read all the answers here and none of them was complete answer for my situation (which is exactly the same in this question) so here is how I gathered some parts of the suggested answers and come up with the exact solution:

1. Land on your server's real 403 page. (Go to a forbidden URL on your server, or go to any 403 page you like)
2. Right-click and select 'view source'. Select all the source and save it to file on your domain like: http://domain.com/403.html
3. now go to your real forbidden page (or a forbidden situation in some part of your php) example: http://domain.com/members/this_is_forbidden.php

4. echo this code below before any HTML output or header! (even a whitespace will cause PHP to send HTML/TEXT HTTP Header and it won't work) The code below should be your first line!

       <?php header('HTTP/1.0 403 Forbidden');
       $contents = file_get_contents('/home/your_account/public_html/domain.com/403.html', TRUE);
       exit($contents);
   

Now you have the exact solution. I checked and verified with CPANEL Latest Visitors and it is registered as exact 403 event.

Just use GETDATE() or GETUTCDATE() (if you want to get the "universal" UTC time, instead of your local server's time-zone related time).

INSERT INTO [Business]
           ([IsDeleted]
           ,[FirstName]
           ,[LastName]
           ,[LastUpdated]
           ,[LastUpdatedBy])
     VALUES
           (0, 'Joe', 'Thomas', 
           GETDATE(),  <LastUpdatedBy, nvarchar(50),>)

Basically there's a program to accomplish that, called "mail". The subject of the email can be specified with a -s and a list of address with -t. You can write the text on your own with the echo command:

echo "This will go into the body of the mail." | mail -s "Hello world" [email protected]

or get it from other files too:

mail -s "Hello world" [email protected] < /home/calvin/application.log

mail doesn't support the sending of attachments, but Mutt does:

echo "Sending an attachment." | mutt -a file.zip -s "attachment" [email protected]

Note that Mutt's much more complete than mail. You can find better explanation here

PS: thanks to @slhck who pointed out that my previous answer was awful. ;)

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/

I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:

function scorePassword(pass) {
    var score = 0;
    if (!pass)
        return score;

    // award every unique letter until 5 repetitions
    var letters = new Object();
    for (var i=0; i<pass.length; i++) {
        letters[pass[i]] = (letters[pass[i]] || 0) + 1;
        score += 5.0 / letters[pass[i]];
    }

    // bonus points for mixing it up
    var variations = {
        digits: /\d/.test(pass),
        lower: /[a-z]/.test(pass),
        upper: /[A-Z]/.test(pass),
        nonWords: /\W/.test(pass),
    }

    var variationCount = 0;
    for (var check in variations) {
        variationCount += (variations[check] == true) ? 1 : 0;
    }
    score += (variationCount - 1) * 10;

    return parseInt(score);
}

Good passwords start to score around 60 or so, here's function to translate that in words:

function checkPassStrength(pass) {
    var score = scorePassword(pass);
    if (score > 80)
        return "strong";
    if (score > 60)
        return "good";
    if (score >= 30)
        return "weak";

    return "";
}

you might want to tune this a bit but i found it working for me nicely

Look at the HttpServletResponse#sendRedirect(String location) method.

Use it as:

response.sendRedirect(request.getContextPath() + "/welcome.jsp")

Alternatively, look at HttpServletResponse#setHeader(String name, String value) method.

The redirection is set by adding the location header:

response.setHeader("Location", request.getContextPath() + "/welcome.jsp");

I think you don't need to update only some specific field. Just update whole data.

@Update query

It is a given query basically. No need to make some new query.

@Dao
interface MemoDao {

    @Insert
    suspend fun insert(memo: Memo)

    @Delete
    suspend fun delete(memo: Memo)

    @Update
    suspend fun update(memo: Memo)
}

Memo.class

@Entity
data class Memo (
    @PrimaryKey(autoGenerate = true) val id: Int,
    @ColumnInfo(name = "title") val title: String?,
    @ColumnInfo(name = "content") val content: String?,
    @ColumnInfo(name = "photo") val photo: List<ByteArray>?
)

Only thing you need to know is 'id'. For instance, if you want to update only 'title', you can reuse 'content' and 'photo' from already inserted data. In real code, use like this

val memo = Memo(id, title, content, byteArrayList)
memoViewModel.update(memo)

The following C++ implementation includes also some code that builds the actual longest increasing subsequence using an array called prev.

std::vector<int> longest_increasing_subsequence (const std::vector<int>& s)
{
    int best_end = 0;
    int sz = s.size();

    if (!sz)
        return std::vector<int>();

    std::vector<int> prev(sz,-1);
    std::vector<int> memo(sz, 0);

    int max_length = std::numeric_limits<int>::min();

    memo[0] = 1;

    for ( auto i = 1; i < sz; ++i)
    {
        for ( auto j = 0; j < i; ++j)
        {
            if ( s[j] < s[i] && memo[i] < memo[j] + 1 )
            {
                memo[i] =  memo[j] + 1;
                prev[i] =  j;
            }
        }

        if ( memo[i] > max_length ) 
        {
            best_end = i;
            max_length = memo[i];
        }
    }

    // Code that builds the longest increasing subsequence using "prev"
    std::vector<int> results;
    results.reserve(sz);

    std::stack<int> stk;
    int current = best_end;

    while (current != -1)
    {
        stk.push(s[current]);
        current = prev[current];
    }

    while (!stk.empty())
    {
        results.push_back(stk.top());
        stk.pop();
    }

    return results;
}

Implementation with no stack just reverse the vector

#include <iostream>
#include <vector>
#include <limits>
std::vector<int> LIS( const std::vector<int> &v ) {
  auto sz = v.size();
  if(!sz)
    return v;
  std::vector<int> memo(sz, 0);
  std::vector<int> prev(sz, -1);
  memo[0] = 1;
  int best_end = 0;
  int max_length = std::numeric_limits<int>::min();
  for (auto i = 1; i < sz; ++i) {
    for ( auto j = 0; j < i ; ++j) {
      if (s[j] < s[i] && memo[i] < memo[j] + 1) {
        memo[i] = memo[j] + 1;
        prev[i] = j;
      }
    }
    if(memo[i] > max_length) {
      best_end = i;
      max_length = memo[i];
    }
  }

  // create results
  std::vector<int> results;
  results.reserve(v.size());
  auto current = best_end;
  while (current != -1) {
    results.push_back(s[current]);
    current = prev[current];
  }
  std::reverse(results.begin(), results.end());
  return results;
}

If I remember my QBasic, right, left and mid do something like this:

>>> s = '123456789'
>>> s[-2:]
'89'
>>> s[:2]
'12'
>>> s[4:6]
'56'

Swift Users

Swift users can check out My Swift Answer for this question.
Or, check out Yedidya Reiss's Answer, which translates this Objective-C code to Swift.

Objective-C Users

The rest of this answer is written in Objective-C

App Store Connect

1. Go to appstoreconnect.apple.com and log in
2. Click My Apps then click the app you want do add the purchase to
3. Click the Features header, and then select In-App Purchases on the left
4. Click the + icon in the middle
5. For this tutorial, we are going to be adding an in-app purchase to remove ads, so choose non-consumable. If you were going to send a physical item to the user, or give them something that they can buy more than once, you would choose consumable.
6. For the reference name, put whatever you want (but make sure you know what it is)
7. For product id put tld.websitename.appname.referencename this will work the best, so for example, you could use com.jojodmo.blix.removeads
8. Choose cleared for sale and then choose price tier as 1 (99¢). Tier 2 would be $1.99, and tier 3 would be $2.99. The full list is available if you click view pricing matrix I recommend you use tier 1, because that's usually the most anyone will ever pay to remove ads.
9. Click the blue add language button, and input the information. This will ALL be shown to the customer, so don't put anything you don't want them seeing
10. For hosting content with Apple choose no
11. You can leave the review notes blank FOR NOW.
12. Skip the screenshot for review FOR NOW, everything we skip we will come back to.
13. Click 'save'

It could take a few hours for your product ID to register in App Store Connect, so be patient.

Setting up your project

Now that you've set up your in-app purchase information on App Store Connect, go into your Xcode project, and go to the application manager (blue page-like icon at the top of where your methods and header files are) click on your app under targets (should be the first one) then go to general. At the bottom, you should see linked frameworks and libraries click the little plus symbol and add the framework StoreKit.framework If you don't do this, the in-app purchase will NOT work!

If you are using Objective-C as the language for your app, you should skip these five steps. Otherwise, if you are using Swift, you can follow My Swift Answer for this question, here, or, if you prefer to use Objective-C for the In-App Purchase code but are using Swift in your app, you can do the following:

1. Create a new .h (header) file by going to File > New > File... (Command ? + N). This file will be referred to as "Your .h file" in the rest of the tutorial

2. When prompted, click Create Bridging Header. This will be our bridging header file. If you are not prompted, go to step 3. If you are prompted, skip step 3 and go directly to step 4.

3. Create another .h file named Bridge.h in the main project folder, Then go to the Application Manager (the blue page-like icon), then select your app in the Targets section, and click Build Settings. Find the option that says Swift Compiler - Code Generation, and then set the Objective-C Bridging Header option to Bridge.h

4. In your bridging header file, add the line #import "MyObjectiveCHeaderFile.h", where MyObjectiveCHeaderFile is the name of the header file that you created in step one. So, for example, if you named your header file InAppPurchase.h, you would add the line #import "InAppPurchase.h" to your bridge header file.

5. Create a new Objective-C Methods (.m) file by going to File > New > File... (Command ? + N). Name it the same as the header file you created in step 1. For example, if you called the file in step 1 InAppPurchase.h, you would call this new file InAppPurchase.m. This file will be referred to as "Your .m file" in the rest of the tutorial.

Coding

Now we're going to get into the actual coding. Add the following code into your .h file:

BOOL areAdsRemoved;

- (IBAction)restore;
- (IBAction)tapsRemoveAds;

Next, you need to import the StoreKit framework into your .m file, as well as add SKProductsRequestDelegate and SKPaymentTransactionObserver after your @interface declaration:

#import <StoreKit/StoreKit.h>

//put the name of your view controller in place of MyViewController
@interface MyViewController() <SKProductsRequestDelegate, SKPaymentTransactionObserver>

@end

@implementation MyViewController //the name of your view controller (same as above)
  //the code below will be added here
@end

and now add the following into your .m file, this part gets complicated, so I suggest that you read the comments in the code:

//If you have more than one in-app purchase, you can define both of
//of them here. So, for example, you could define both kRemoveAdsProductIdentifier
//and kBuyCurrencyProductIdentifier with their respective product ids
//
//for this example, we will only use one product

#define kRemoveAdsProductIdentifier @"put your product id (the one that we just made in App Store Connect) in here"

- (IBAction)tapsRemoveAds{
    NSLog(@"User requests to remove ads");

    if([SKPaymentQueue canMakePayments]){
        NSLog(@"User can make payments");
    
        //If you have more than one in-app purchase, and would like
        //to have the user purchase a different product, simply define 
        //another function and replace kRemoveAdsProductIdentifier with 
        //the identifier for the other product

        SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
        productsRequest.delegate = self;
        [productsRequest start];
    
    }
    else{
        NSLog(@"User cannot make payments due to parental controls");
        //this is called the user cannot make payments, most likely due to parental controls
    }
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *validProduct = nil;
    int count = [response.products count];
    if(count > 0){
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products Available!");
        [self purchase:validProduct];
    }
    else if(!validProduct){
        NSLog(@"No products available");
        //this is called if your product id is not valid, this shouldn't be called unless that happens.
    }
}

- (void)purchase:(SKProduct *)product{
    SKPayment *payment = [SKPayment paymentWithProduct:product];

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (IBAction) restore{
    //this is called when the user restores purchases, you should hook this up to a button
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for(SKPaymentTransaction *transaction in queue.transactions){
        if(transaction.transactionState == SKPaymentTransactionStateRestored){
            //called when the user successfully restores a purchase
            NSLog(@"Transaction state -> Restored");

            //if you have more than one in-app purchase product,
            //you restore the correct product for the identifier.
            //For example, you could use
            //if(productID == kRemoveAdsProductIdentifier)
            //to get the product identifier for the
            //restored purchases, you can use
            //
            //NSString *productID = transaction.payment.productIdentifier;
            [self doRemoveAds];
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        }
    }   
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
    for(SKPaymentTransaction *transaction in transactions){
        //if you have multiple in app purchases in your app,
        //you can get the product identifier of this transaction
        //by using transaction.payment.productIdentifier
        //
        //then, check the identifier against the product IDs
        //that you have defined to check which product the user
        //just purchased            

        switch(transaction.transactionState){
            case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
                //called when the user is in the process of purchasing, do not add any of your own code here.
                break;
            case SKPaymentTransactionStatePurchased:
            //this is called when the user has successfully purchased the package (Cha-Ching!)
                [self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                NSLog(@"Transaction state -> Purchased");
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"Transaction state -> Restored");
                //add the same code as you did from SKPaymentTransactionStatePurchased here
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                //called when the transaction does not finish
                if(transaction.error.code == SKErrorPaymentCancelled){
                    NSLog(@"Transaction state -> Cancelled");
                    //the user cancelled the payment ;(
                }
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
        }
    }
}

Now you want to add your code for what will happen when the user finishes the transaction, for this tutorial, we use removing adds, you will have to add your own code for what happens when the banner view loads.

- (void)doRemoveAds{
    ADBannerView *banner;
    [banner setAlpha:0];
    areAdsRemoved = YES;
    removeAdsButton.hidden = YES;
    removeAdsButton.enabled = NO;
    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load whether or not they bought it
    //it would be better to use KeyChain access, or something more secure
    //to store the user data, because NSUserDefaults can be changed.
    //You're average downloader won't be able to change it very easily, but
    //it's still best to use something more secure than NSUserDefaults.
    //For the purpose of this tutorial, though, we're going to use NSUserDefaults
    [[NSUserDefaults standardUserDefaults] synchronize];
}

If you don't have ads in your application, you can use any other thing that you want. For example, we could make the color of the background blue. To do this we would want to use:

- (void)doRemoveAds{
    [self.view setBackgroundColor:[UIColor blueColor]];
    areAdsRemoved = YES
    //set the bool for whether or not they purchased it to YES, you could use your own boolean here, but you would have to declare it in your .h file

    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load wether or not they bought it
    [[NSUserDefaults standardUserDefaults] synchronize];
}

Now, somewhere in your viewDidLoad method, you're going to want to add the following code:

areAdsRemoved = [[NSUserDefaults standardUserDefaults] boolForKey:@"areAdsRemoved"];
[[NSUserDefaults standardUserDefaults] synchronize];
//this will load wether or not they bought the in-app purchase

if(areAdsRemoved){
    [self.view setBackgroundColor:[UIColor blueColor]];
    //if they did buy it, set the background to blue, if your using the code above to set the background to blue, if your removing ads, your going to have to make your own code here
}

Now that you have added all the code, go into your .xib or storyboard file, and add two buttons, one saying purchase, and the other saying restore. Hook up the tapsRemoveAds IBAction to the purchase button that you just made, and the restore IBAction to the restore button. The restore action will check if the user has previously purchased the in-app purchase, and give them the in-app purchase for free if they do not already have it.

Submitting for review

Next, go into App Store Connect, and click Users and Access then click the Sandbox Testers header, and then click the + symbol on the left where it says Testers. You can just put in random things for the first and last name, and the e-mail does not have to be real - you just have to be able to remember it. Put in a password (which you will have to remember) and fill in the rest of the info. I would recommend that you make the Date of Birth a date that would make the user 18 or older. App Store Territory HAS to be in the correct country. Next, log out of your existing iTunes account (you can log back in after this tutorial).

Now, run your application on your iOS device, if you try running it on the simulator, the purchase will always error, you HAVE TO run it on your iOS device. Once the app is running, tap the purchase button. When you are prompted to log into your iTunes account, log in as the test user that we just created. Next,when it asks you to confirm the purchase of 99¢ or whatever you set the price tier too, TAKE A SCREEN SNAPSHOT OF IT this is what your going to use for your screenshot for review on App Store Connect. Now cancel the payment.

Now, go to App Store Connect, then go to My Apps > the app you have the In-app purchase on > In-App Purchases. Then click your in-app purchase and click edit under the in-app purchase details. Once you've done that, import the photo that you just took on your iPhone into your computer, and upload that as the screenshot for review, then, in review notes, put your TEST USER e-mail and password. This will help apple in the review process.

After you have done this, go back onto the application on your iOS device, still logged in as the test user account, and click the purchase button. This time, confirm the payment Don't worry, this will NOT charge your account ANY money, test user accounts get all in-app purchases for free After you have confirmed the payment, make sure that what happens when the user buys your product actually happens. If it doesn't, then thats going to be an error with your doRemoveAds method. Again, I recommend using changing the background to blue for testing the in-app purchase, this should not be your actual in-app purchase though. If everything works and you're good to go! Just make sure to include the in-app purchase in your new binary when you upload it to App Store Connect!

Here are some common errors:

Logged: No Products Available

This could mean four things:

• You didn't put the correct in-app purchase ID in your code (for the identifier kRemoveAdsProductIdentifier in the above code
• You didn't clear your in-app purchase for sale on App Store Connect
• You didn't wait for the in-app purchase ID to be registered in App Store Connect. Wait a couple hours from creating the ID, and your problem should be resolved.
• You didn't complete filling your Agreements, Tax, and Banking info.

If it doesn't work the first time, don't get frustrated! Don't give up! It took me about 5 hours straight before I could get this working, and about 10 hours searching for the right code! If you use the code above exactly, it should work fine. Feel free to comment if you have any questions at all.

I hope this helps to all of those hoping to add an in-app purchase to their iOS application. Cheers!

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

For all date related functionality, you should consider using Joda Library. Java's date api's are very poorly designed. Joda provides very nice API.

If you wanted to keep it with just HTML and CSS you can use CSS Variables. Keep in mind, css variables aren't supported in IE.

<div class="thumb" style="--background: url('images/img.jpg')"></div> 

.thumb {
    background-image: var(--background);
}

You need to use IFS to stop space as element delimiter.

FILES=("2011-09-04 21.43.02.jpg"
       "2011-09-05 10.23.14.jpg"
       "2011-09-09 12.31.16.jpg"
       "2011-09-11 08.43.12.jpg")
IFS=""
for jpg in ${FILES[*]}
do
    echo "${jpg}"
done

If you want to separate on basis of . then just do IFS="." Hope it helps you:)

Python has several things that fulfill similar purposes:

• One common way to build large strings from pieces is to grow a list of strings and join it when you are done. This is a frequently-used Python idiom.
  • To build strings incorporating data with formatting, you would do the formatting separately.
• For insertion and deletion at a character level, you would keep a list of length-one strings. (To make this from a string, you'd call list(your_string). You could also use a UserString.MutableString for this.
• (c)StringIO.StringIO is useful for things that would otherwise take a file, but less so for general string building.

use labelpad parameter:

pl.xlabel("...", labelpad=20)

or set it after:

ax.xaxis.labelpad = 20

Actually, ANDROID_ID on 2.2 always equals 9774D56D682E549C (according to this thread + my own experiments).

So, you could check something like this:

String androidID = ...;
if(androidID == null || androidID.equals("9774D56D682E549C"))
    do stuff;

Not the prettiest, but it does the job.

How to select all children of an element except the last child using CSS?

Answer: this code will work

<style>
.parent *:not(:last-child) { 
  color:red;
}
</style>

<div class='parent'>
  <p>this is paragraph</p>
  <h1>this is heading</h1>
  <b>text is bold</b>
</div>

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

You could do the following:

• Let the shutdown hook set some AtomicBoolean (or volatile boolean) "keepRunning" to false
• (Optionally, .interrupt the working threads if they wait for data in some blocking call)
• Wait for the working threads (executing writeBatch in your case) to finish, by calling the Thread.join() method on the working threads.
• Terminate the program

Some sketchy code:

• Add a static volatile boolean keepRunning = true;

• In run() you change to

  for (int i = 0; i < N && keepRunning; ++i)
      writeBatch(pw, i);
  

• In main() you add:

  final Thread mainThread = Thread.currentThread();
  Runtime.getRuntime().addShutdownHook(new Thread() {
      public void run() {
          keepRunning = false;
          mainThread.join();
      }
  });
  

That's roughly how I do a graceful "reject all clients upon hitting Control-C" in terminal.

From the docs:

When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine will halt.

That is, a shutdown hook keeps the JVM running until the hook has terminated (returned from the run()-method.

$('#toggle').click(function() {
  $('#B').toggleClass('extended-panel');
  $('#A').toggle(/** specify a time here for an animation */);
});

and in the CSS:

.extended-panel {
  left: 0px !important;
}

A very simple approach:

def progbar(count: int) -> None:
    for i in range(count):
        print(f"[{i*'#'}{(count-1-i)*' '}] - {i+1}/{count}", end="\r")
        yield i
    print('\n')

And the usage:

from time import sleep

for i in progbar(10):
    sleep(0.2) #whatever task you need to do

You can use COALESCE

SELECT COALESCE(SUM(column),0)
FROM   table

OK,

One of the more difficult concepts to grasp about Excel VSTO programming is that you don't refer to cells like an array, Worksheet[0][0] won't give you cell A1, it will error out on you. Even when you type into A1 when Excel is open, you are actually entering data into Range A1. Therefore you refer to cells as Named Ranges. Here's an example:

Excel.Worksheet sheet = workbook.Sheets["Sheet1"] as Excel.Worksheet; 
Excel.Range range = sheet.get_Range("A1", Missing.Value)

You can now literally type:

range.Text // this will give you the text the user sees
range.Value2 // this will give you the actual value stored by Excel (without rounding)

If you want to do something like this:

Excel.Range range = sheet.get_Range("A1:A5", Missing.Value)

if (range1 != null)
     foreach (Excel.Range r in range1)
     {
         string user = r.Text
         string value = r.Value2

     }

There might be a better way, but this has worked for me.

The reason you need to use Value2 and not Value is because the Value property is a parametrized and C# doesn't support them yet.

As for the cleanup code, i will post that when i get to work tomorrow, i don't have the code with me, but it's very boilerplate. You just close and release the objects in the reverse order you created them. You can't use a Using() block because the Excel.Application or Excel.Workbook doesn't implement IDisposable, and if you don't clean-up, you will be left with a hanging Excel objects in memory.

Note:

• If you don't set the Visibility property Excel doesn't display, which can be disconcerting to your users, but if you want to just rip the data out, that is probably good enough
• You could OleDb, that will work too.

I hope that gets you started, let me know if you need further clarification. I'll post a complete

here is a complete sample:

using System;
using System.IO;
using System.Reflection;
using NUnit.Framework;
using ExcelTools = Ms.Office;
using Excel = Microsoft.Office.Interop.Excel;

namespace Tests
{
    [TestFixture]
    public class ExcelSingle
    {
        [Test]
        public void ProcessWorkbook()
        {
            string file = @"C:\Users\Chris\Desktop\TestSheet.xls";
            Console.WriteLine(file);

            Excel.Application excel = null;
            Excel.Workbook wkb = null;

            try
            {
                excel = new Excel.Application();

                wkb = ExcelTools.OfficeUtil.OpenBook(excel, file);

                Excel.Worksheet sheet = wkb.Sheets["Data"] as Excel.Worksheet;

                Excel.Range range = null;

                if (sheet != null)
                    range = sheet.get_Range("A1", Missing.Value);

                string A1 = String.Empty;

                if( range != null )
                    A1 = range.Text.ToString();

                Console.WriteLine("A1 value: {0}", A1);

            }
            catch(Exception ex)
            {
                //if you need to handle stuff
                Console.WriteLine(ex.Message);
            }
            finally
            {
                if (wkb != null)
                    ExcelTools.OfficeUtil.ReleaseRCM(wkb);

                if (excel != null)
                    ExcelTools.OfficeUtil.ReleaseRCM(excel);
            }
        }
    }
}

I'll post the functions from ExcelTools tomorrow, I don't have that code with me either.

Edit: As promised, here are the Functions from ExcelTools you might need.

public static Excel.Workbook OpenBook(Excel.Application excelInstance, string fileName, bool readOnly, bool editable,
        bool updateLinks) {
        Excel.Workbook book = excelInstance.Workbooks.Open(
            fileName, updateLinks, readOnly,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, editable, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing);
        return book;
    }

public static void ReleaseRCM(object o) {
        try {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(o);
        } catch {
        } finally {
            o = null;
        }
    }

To be frank, this stuff is much easier if you use VB.NET. It's in C# because I didn't write it. VB.NET does option parameters well, C# does not, hence the Type.Missing. Once you typed Type.Missing twice in a row, you run screaming from the room!

As for you question, you can try to following:

http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.range.find(VS.80).aspx

I will post an example when I get back from my meeting... cheers

Edit: Here is an example

range = sheet.Cells.Find("Value to Find",
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Excel.XlSearchDirection.xlNext,
                                                 Type.Missing,
                                                 Type.Missing, Type.Missing);

range.Text; //give you the value found

Here is another example inspired by this site:

 range = sheet.Cells.Find("Value to find", Type.Missing, Type.Missing,Excel.XlLookAt.xlWhole,Excel.XlSearchOrder.xlByColumns,Excel.XlSearchDirection.xlNext,false, false, Type.Missing);

It helps to understand the parameters.

P.S. I'm one of those weird people who enjoys learning COM automation. All this code steamed from a tool I wrote for work which required me to process over 1000+ spreadsheets from the lab each Monday.

You can use .replaceWith()

$(function() {_x000D_
_x000D_
  $(".region").click(function(e) {_x000D_
    e.preventDefault();_x000D_
    var content = $(this).html();_x000D_
    $('#map').replaceWith('<div class="region">' + content + '</div>');_x000D_
  });_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="map">_x000D_
  <div class="region"><a href="link1">region1</a></div>_x000D_
  <div class="region"><a href="link2">region2</a></div>_x000D_
  <div class="region"><a href="link3">region3</a></div>_x000D_
</div>

I find this way more readable:

$result = $mysqli->query('select count(*) as `c` from `table`');
$count = $result->fetch_object()->c;
echo "there are {$count} rows in the table";

Not that I have anything against arrays...

Honestly I don't find there to be many cases where IoC containers are needed, and most of the time, they just add unneeded complexity.

If you are using it just for making construction of an object simpler, I'd have to ask, are you instantiating this object in more than one location? Would a singleton not suit your needs? Are you changing the configuration at runtime? (Switching data source types, etc).

If yes, then you might need an IoC container. If not, then you're just moving the initialization away from where the developer can easily see it.

Who said that an interface is better than inheritance anyway? Say you're testing a Service. Why not use constructor DI, and create mocks of the dependencies using inheritance? Most services I use only have a few dependencies. Doing unit testing this way prevents maintaining a ton of useless interfaces and means you don't have to use Resharper to quickly find the declaration of a method.

I believe that for most implementations, saying that IoC Containers remove unneeded code is a myth.

First, there's setting up the container in the first place. Then you still have to define each object that needs to be initialized. So you don't save code in initialization, you move it (unless your object is used more than once. Is it better as a Singleton?). Then, for each object you've initialized in this way, you have to create and maintain an interface.

Anyone have any thoughts on this?

You could extend FutureTask class, and override the done() method, then add the FutureTask object to the ExecutorService, so the done() method will invoke when the FutureTask completed immediately.

double formattedNumber = Double.parseDouble(new DecimalFormat("#.##").format(unformattedNumber));

worked for me :)

You sure the timer isn't outliving the 'dbiSchedule' somehow and firing after the 'dbiSchedule' has been been disposed of?

If that is the case you might be able to recreate it more consistently if the timer fires more quickly thus increasing the chances of you closing the Form just as the timer is firing.

If you are looking for PERFORMANCE, give where condition inside the db link query. Otherwise it fetch all data from the foreign table and apply the where condition.

INSERT INTO tblA (id,time) 
SELECT id, time FROM  dblink('dbname=dbname port=5432 host=10.10.90.190 user=postgresuser password=pass123', 
'select id, time from tblB  where time>'''||1000||'''')
AS t1(id integer, time integer)  

You can use this;

QString data;
data.toStdString().c_str();

Escape the percent sign \% to make it part of your comparison value.

It's a class that cannot be instantiated, and forces implementing classes to, possibly, implement abstract methods that it outlines.

No need to modify the Makefile.

$ cat printvars.mak
print-%:
        @echo '$*=$($*)'

$ cd /to/Makefile/dir
$ make -f ~/printvars.mak -f Makefile print-VARIABLE

First of all, you are in a bad position now - having the task of writing tests for the code you did not originally create and without any changes - nightmare! Talk to your boss and explain, it is not possible to test the code without making it "testable". To make code testable you usually do some important changes;

Regarding private variables. You actually never should do that. Aiming to test private variables is the first sign that something wrong with the current design. Private variables are part of the implementation, tests should focus on behavior rather of implementation details.

Sometimes, private field are exposed to public access with some getter. I do that, but try to avoid as much as possible (mark in comments, like 'used for testing').

Since you have no possibility to change the code, I don't see possibility (I mean real possibility, not like Reflection hacks etc.) to check private variable.

There are multiple good answers here, and some less robust ones. Here's an overview.

How not to do it

Do not rely on on the location of Python or the site-packages folder.

If these are set to non-standard locations, that does not mean you're actually in a virtual environment. Users can have more than one Python version installed, and those are not always where you expect them to be.

Avoid looking at:

• sys.executable
• sys.prefix
• pip -V
• which python

Also, do not check for the presence of venv, .venv or envs in any of these paths. This will break for environments with a more unique location. For example, Pipenv uses hash values as the name for its environments.

VIRTUAL_ENV environment variable

Both virtualenv and venv set the environment variable $VIRTUAL_ENV when activating an environment. See PEP 405.

You can read out this variable in shell scripts, or use this Python code to determine if it's set.

import os
running_in_virtualenv = "VIRTUAL_ENV" in os.environ

# alternative ways to write this, also supporting the case where
# the variable is set but contains an empty string to indicate
# 'not in a virtual environment':
running_in_virtualenv = bool(os.environ.get("VIRTUAL_ENV"))
running_in_virtualenv = bool(os.getenv("VIRTUAL_ENV"))

The problem is, this only works when the environment is activated by the activate shell script.

You can start the environment's scripts without activating the environment, so if that is a concern, you have to use a different method.

sys.base_prefix

virtualenv, venv and pyvenv point sys.prefix to the Python installed inside of the virtualenv as you would expect.

At the same time, the original value of sys.prefix is also made available as sys.base_prefix.

We can use that to detect if we're in a virtualenv.

import sys
# note: Python versions before 3.3 don't have sys.base_prefix
# if you're not in virtual environment
running_in_virtualenv = sys.prefix != sys.base_prefix

Fallback: sys.real_prefix

Now watch out, virtualenv before version 20 did not set sys.base_prefix but it set sys.real_prefix instead.

So to be safe, check both as suggested in hroncok's answer:

import sys

real_prefix = getattr(sys, "real_prefix", None)
base_prefix = getattr(sys, "base_prefix", sys.prefix)

running_in_virtualenv = (base_prefix or real_prefix) != sys.prefix

Anaconda

If you're using Anaconda virtual environments, check Victoria Stuart's answer.

At first I would use http://ruby.railstutorial.org/.

And database.yml is place where you put setup for database your application use - username, password, host - for each database. With new application you dont need to change anything - simply use default sqlite setup.

The code creates an anonymous function, and then immediately runs it. Similar to:

var temp = function() {
  // init part
}
temp();

The purpose of this construction is to create a scope for the code inside the function. You can declare varaibles and functions inside the scope, and those will be local to that scope. That way they don't clutter up the global scope, which minimizes the risk for conflicts with other scripts.

The Placeholder does not render any tags for itself, so it is great for grouping content without the overhead of outer HTML tags.

The Panel does have outer HTML tags but does have some cool extra properties.

• BackImageUrl: Gets/Sets the background image's URL for the panel

• HorizontalAlign: Gets/Sets the
  horizontal alignment of the parent's contents

• Wrap: Gets/Sets whether the
  panel's content wraps

There is a good article at startvbnet here.

In Python 2, division of two ints produces an int. In Python 3, it produces a float. We can get the new behaviour by importing from __future__.

>>> from __future__ import division
>>> a = 4
>>> b = 6
>>> c = a / b
>>> c
0.66666666666666663

NOTE: This should be considered a discussion rather than an actual answer.

An approximate approach is to operate __main__ in the module you want to create variables. For example there's a b.py:

#!/usr/bin/env python
# coding: utf-8


def set_vars():
    import __main__
    print '__main__', __main__
    __main__.B = 1

try:
    print B
except NameError as e:
    print e

set_vars()

print 'B: %s' % B

Running it would output

$ python b.py
name 'B' is not defined
__main__ <module '__main__' from 'b.py'>
B: 1

But this approach only works in a single module script, because the __main__ it import will always represent the module of the entry script being executed by python, this means that if b.py is involved by other code, the B variable will be created in the scope of the entry script instead of in b.py itself. Assume there is a script a.py:

#!/usr/bin/env python
# coding: utf-8

try:
    import b
except NameError as e:
    print e

print 'in a.py: B', B

Running it would output

$ python a.py
name 'B' is not defined
__main__ <module '__main__' from 'a.py'>
name 'B' is not defined
in a.py: B 1

Note that the __main__ is changed to 'a.py'.

What directory is file.txt in? cron runs jobs in your home directory, so unless your script cds somewhere else, that's where it's going to look for/create file.txt.

EDIT: When you refer to a file without specifying its full path (e.g. file.txt, as opposed to the full path /home/myUser/scripts/file.txt) in shell, it's taken that you're referring to a file in your current working directory. When you run a script (whether interactively or via crontab), the script's working directory has nothing at all to do with the location of the script itself; instead, it's inherited from whatever ran the script.

Thus, if you cd (change working directory) to the directory the script's in and then run it, file.txt will refer to a file in the same directory as the script. But if you don't cd there first, file.txt will refer to a file in whatever directory you happen to be in when you ran the script. For instance, if your home directory is /home/myUser, and you open a new shell and immediately run the script (as scripts/test.sh or /home/myUser/scripts/test.sh; ./test.sh won't work), it'll touch the file /home/myUser/file.txt because /home/myUser is your current working directory (and therefore the script's).

When you run a script from cron, it does essentially the same thing: it runs it with the working directory set to your home directory. Thus all file references in the script are taken relative to your home directory, unless the script cds somewhere else or specifies an absolute path to the file.

First Step you need to create a list instance through Arrays.asList();

String[] args = new String[]{"one","two","three"};
List<String> list = Arrays.asList(args);//it converts to immutable list

Then you need to pass 'list' instance to new ArrayList();

List<String> newList=new ArrayList<>(list);

In My case I have't define all variables which I am passing to data in ajax.

var page = 1;

$.ajax({
    url: 'your_url',
    type: "post",
    data: { 'page' : page, 'search_candidate' : search_candidate }
    success: function(result){
        alert('function called');
    }
)}

I have just defined variable var search_candidate = "candidate name"; and its working.

var page = 1;
var search_candidate = "candidate name"; // defined
$.ajax({
    url: 'your_url',
    type: "post",
    data: { 'page' : page, 'search_candidate' : search_candidate }
    success: function(result){
        alert('function called');
    }

I also struggled with this same issue. But I was able to manage this problem by using following code segment. Use this in your blade template.

<input type="hidden" value="{{$old_section = "whatever" }}">

{{$old_section }}

If the excel file is password protected, then this error comes up.

For a side-by-side visual representation, I use git difftool with openDiff set to the default viewer.

Example usage:

git difftool tags/<FIRST TAG> tags/<SECOND TAG>

If you are only interested in a specific file, you can use:

git difftool tags/<FIRST TAG>:<FILE PATH> tags/<SECOND TAG>:<FILE PATH>

As a side-note, the tags/<TAG>s can be replaced with <BRANCH>es if you are interested in diffing branches.

I solved this by assigning a ref to the component and then checking if the ref exists before setting the state:

myMethod(){
  if (this.refs.myRef) 
   this.setState({myVar: true});
}

render() {
  return (
    <div ref="myRef">
      {this.state.myVar}
    </div>
  );
}

And lately, since I am using mostly functional components, I am using this pattern:

const Component = () => {
  const ref = React.useRef(null);
  const [count, setCount] = React.useState(0);

  const increment = () => {
    setTimeout(() => { // usually fetching API data here
      if (ref.current !== null) {
        setCount((count) => count + 1);
      }
    }, 100);
  };

  return (
    <button onClick={increment} ref={ref}>
      Async Increment {count}
    </button>
  );
};

From Apache Commons library:

import org.apache.commons.lang3.StringUtils

Use:

StringUtils.join(slist, ',');

Another similar question and answer here

If your arrays are character arrays(which seems to be the case), You need a strcat().
Your destination array should have enough space to accommodate the appended data though.

In C++, You are much better off using std::string and then you can use std::string::append()

For me the problem was that I was running the migrate command not from inside the container where php was running. The extension was properly set there but not at my host machine.

I had the same problem. Here are the steps for Windows 10 users.

Open CMD: win+r then type cmd. Now,

1. Type pip install virtualenv
2. Create a Virtual Environment, Type virtualenv testopencv
3. Get Inside testopencv, Type cd testopencv
4. Activate the Virtual Environment, Type .\Scripts\activate
5. Now Install Opencv, Type pip install opencv-contrib-python --upgrade
6. Let's test Opencv, Type Python then import cv2 hit enter then type print(cv2.__version__) to check if its installed

Now, open a new cmd, win + r then type cmd, repeat step 6. If it gives you an error.

Go inside the testopencv folder, inside lib. Copy everything, go to your python directory, inside lib folder paste it and skip that are already present.

Again open a new cmd, repeat Step 6.

Hope it helps.

Thank you all for responding. After a further investigation I got to the right answer. As mentioned by Skip Head, the TimeStamped I was getting from my application was being adjusted to the user's TimeZone. So if the User entered 6:12 PM (EST) I would get 2:12 PM (GMT). What I needed was a way to undo the conversion so that the time entered by the user is the time I sent to the WebServer request. Here's how I accomplished this:

// Get TimeZone of user
TimeZone currentTimeZone = sc_.getTimeZone();
Calendar currentDt = new GregorianCalendar(currentTimeZone, EN_US_LOCALE);
// Get the Offset from GMT taking DST into account
int gmtOffset = currentTimeZone.getOffset(
    currentDt.get(Calendar.ERA), 
    currentDt.get(Calendar.YEAR), 
    currentDt.get(Calendar.MONTH), 
    currentDt.get(Calendar.DAY_OF_MONTH), 
    currentDt.get(Calendar.DAY_OF_WEEK), 
    currentDt.get(Calendar.MILLISECOND));
// convert to hours
gmtOffset = gmtOffset / (60*60*1000);
System.out.println("Current User's TimeZone: " + currentTimeZone.getID());
System.out.println("Current Offset from GMT (in hrs):" + gmtOffset);
// Get TS from User Input
Timestamp issuedDate = (Timestamp) getACPValue(inputs_, "issuedDate");
System.out.println("TS from ACP: " + issuedDate);
// Set TS into Calendar
Calendar issueDate = convertTimestampToJavaCalendar(issuedDate);
// Adjust for GMT (note the offset negation)
issueDate.add(Calendar.HOUR_OF_DAY, -gmtOffset);
System.out.println("Calendar Date converted from TS using GMT and US_EN Locale: "
    + DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT)
    .format(issueDate.getTime()));

The code's output is: (User entered 5/1/2008 6:12PM (EST)

Current User's TimeZone: EST
Current Offset from GMT (in hrs):-4 (Normally -5, except is DST adjusted)
TS from ACP: 2008-05-01 14:12:00.0
Calendar Date converted from TS using GMT and US_EN Locale: 5/1/08 6:12 PM (GMT)

At the very core, the file extension you use makes no difference as to how perl interprets those files.

However, putting modules in .pm files following a certain directory structure that follows the package name provides a convenience. So, if you have a module Example::Plot::FourD and you put it in a directory Example/Plot/FourD.pm in a path in your @INC, then use and require will do the right thing when given the package name as in use Example::Plot::FourD.

The file must return true as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with 1; unless you're sure it'll return true otherwise. But it's better just to put the 1;, in case you add more statements.

If EXPR is a bareword, the require assumes a ".pm" extension and replaces "::" with "/" in the filename for you, to make it easy to load standard modules. This form of loading of modules does not risk altering your namespace.

All use does is to figure out the filename from the package name provided, require it in a BEGIN block and invoke import on the package. There is nothing preventing you from not using use but taking those steps manually.

For example, below I put the Example::Plot::FourD package in a file called t.pl, loaded it in a script in file s.pl.

C:\Temp> cat t.pl
package Example::Plot::FourD;

use strict; use warnings;

sub new { bless {} => shift }

sub something { print "something\n" }

"Example::Plot::FourD"

C:\Temp> cat s.pl
#!/usr/bin/perl
use strict; use warnings;

BEGIN {
    require 't.pl';
}

my $p = Example::Plot::FourD->new;
$p->something;


C:\Temp> s
something

This example shows that module files do not have to end in 1, any true value will do.

We have function total_seconds() with Python 2.7 Please see below code for python 2.6

import datetime
import time  

def diffdates(d1, d2):
    #Date format: %Y-%m-%d %H:%M:%S
    return (time.mktime(time.strptime(d2,"%Y-%m-%d %H:%M:%S")) -
               time.mktime(time.strptime(d1, "%Y-%m-%d %H:%M:%S")))

d1 = datetime.now()
d2 = datetime.now() + timedelta(days=1)
diff = diffdates(d1, d2)

Try This

this example is one directory back

require_once('../images/yourimg.png');

this example is two directory back

A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.

Kolorobot’s example application includes the following:

• No-xml Spring MVC 3.2 web application for Servlet 3.0 environment
• Apache Tiles with configuration in place,
• Bootstrap
• JPA 2.0 (Hibernate/HSQLDB)
• JUnit/Mockito
• Spring Security 3.1

Inspired by the comment of @MitMaro, I wrote a small benchmark to test the speed of solutions of @Gumbo, @Matt Bridges and @justin the proposal in the question:

function teststrtok($number_of_tests){
    for($i = 0; $i < $number_of_tests; $i++){
      $str = "http://www.example.com?test=test";
      $str = strtok($str,'?');
    }
}
function testexplode($number_of_tests){
    for($i = 0; $i < $number_of_tests; $i++){
      $str = "http://www.example.com?test=test";
      $str = explode('?', $str);
    }
}
function testregexp($number_of_tests){
    for($i = 0; $i < $number_of_tests; $i++){
      $str = "http://www.example.com?test=test";
      preg_replace('/\\?.*/', '', $str);
    }
}
function teststrpos($number_of_tests){
    for($i = 0; $i < $number_of_tests; $i++){
      $str = "http://www.example.com?test=test";
      $qPos = strpos($str, "?");
      $url_without_query_string = substr($str, 0, $qPos);
    }
}

$number_of_runs = 10;
for($runs = 0; $runs < $number_of_runs; $runs++){

  $number_of_tests = 40000;
  $functions = array("strtok", "explode", "regexp", "strpos");
  foreach($functions as $func){
    $starttime = microtime(true);
    call_user_func("test".$func, $number_of_tests);
    echo $func.": ". sprintf("%0.2f",microtime(true) - $starttime).";";
  }
  echo "<br />";
}

strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;
strtok: 0.12;explode: 0.19;regexp: 0.31;strpos: 0.18;

Result: @justin's strtok is the fastest.

Note: tested on a local Debian Lenny system with Apache2 and PHP5.

Note: the style goes in between the head tag (<head> .... </head>) and the class="class1" and the id="nav_menu" goes in the ie: (-- <span class="class1" id="nav_menu"> --).

Then the last class attribute (class="current") goes in the hyper-link code of the link in the page that you want the active current link to correspond to.

Example: You want the link tab to stay active or highlighted when it's correspondent page is whats currently in view, go to that page itself and place the class="current" attribute by it's link's html code. Only in the page that corresponds to the link so that when ever that page is at view, the tab will stay highlighted or stand out different from the rest of the tabs.

For the Home page, go to the home page and place the class in it. example: <a href="http://Yourhomepage-url.com/" class="current" target="_parent">

For the About page, go to the about page and place the class in it. example: <a href="http://Yourhomepage-url.com/youraboutpage-url.php_or_.html" class="current" target="_parent">

For the Contact page, go to the contact page and place the class in it. example: <a href="http://Yourhomepage-url.com/youraboutpage-url.php_or_.html" class="current" target="_parent">

etc ......

Notice the example Table above;- Lets assume this was the Home page, so on this page, only the Home url link section has the class="current"

Sorry for any meaning-less error, am not a prof. but this worked for me and displays fine in almost all the browsers tested, including ipad, and smart phones. Hope this will help some-one out here because is very frustrating to want to and not able to. I had tried so had to get to this, and so far it's good for me.

john smith -> John Smith

If you must create an empty array you can do this:

string[] arr = new string[0];

If you don't know about the size then You may also use List<string> as well like

var valStrings = new List<string>();

// do stuff...

string[] arrStrings = valStrings.ToArray();

How about

when( method-call ).thenReturn( value1, value2, value3 );

You can put as many arguments as you like in the brackets of thenReturn, provided they're all the correct type. The first value will be returned the first time the method is called, then the second answer, and so on. The last value will be returned repeatedly once all the other values are used up.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

Get and Set

Get

string getEnv = Environment.GetEnvironmentVariable("envVar");

Set

string setEnv = Environment.SetEnvironmentVariable("envvar", varEnv);

Your curl command is entirely wrong. You should be using the following

curl -H 'Authorization: token <MYTOKEN>' ...

That aside, that doesn't authorize your computer to clone the repository if in fact it is private. (Taking a look, however, indicates that it is not.) What you would normally do is the following:

git clone https://scuzzlebuzzle:<MYTOKEN>@github.com/scuzzlebuzzle/ol3-1.git --branch=gh-pages gh-pages

That will add your credentials to the remote created when cloning the repository. Unfortunately, however, you have no control over how Travis clones your repository, so you have to edit the remote like so.

# After cloning
cd gh-pages
git remote set-url origin https://scuzzlebuzzle:<MYTOKEN>@github.com/scuzzlebuzzle/ol3-1.git

That will fix your project to use a remote with credentials built in.

Warning: Tokens have read/write access and should be treated like passwords. If you enter your token into the clone URL when cloning or adding a remote, Git writes it to your .git/config file in plain text, which is a security risk.

http://curl.haxx.se/docs/httpscripting.html

See part 6. HTTP Authentication

HTTP Authentication

HTTP Authentication is the ability to tell the server your username and password so that it can verify that you're allowed to do the request you're doing. The Basic authentication used in HTTP (which is the type curl uses by default) is plain text based, which means it sends username and password only slightly obfuscated, but still fully readable by anyone that sniffs on the network between you and the remote server.

To tell curl to use a user and password for authentication:

curl --user name:password http://www.example.com

The site might require a different authentication method (check the headers returned by the server), and then --ntlm, --digest, --negotiate or even --anyauth might be options that suit you.

Sometimes your HTTP access is only available through the use of a HTTP proxy. This seems to be especially common at various companies. A HTTP proxy may require its own user and password to allow the client to get through to the Internet. To specify those with curl, run something like:

curl --proxy-user proxyuser:proxypassword curl.haxx.se

If your proxy requires the authentication to be done using the NTLM method, use --proxy-ntlm, if it requires Digest use --proxy-digest.

If you use any one these user+password options but leave out the password part, curl will prompt for the password interactively.

Do note that when a program is run, its parameters might be possible to see when listing the running processes of the system. Thus, other users may be able to watch your passwords if you pass them as plain command line options. There are ways to circumvent this.

It is worth noting that while this is how HTTP Authentication works, very many web sites will not use this concept when they provide logins etc. See the Web Login chapter further below for more details on that.

Here is what I'm doing very easily: I modified my base.html file for my template and put that at the bottom:

{% if DJdata %}
    <script type="text/javascript">
        (function () {window.DJdata = {{DJdata|safe}};})();
    </script>
{% endif %}

then when I want to use a variable in the javascript files, I create a DJdata dictionary and I add it to the context by a json : context['DJdata'] = json.dumps(DJdata)

Hope it helps!

You can use a closure call setTimeout() with incrementally larger values.

var items = ['item1', 'item2', 'item3'];

function functionToExecute(item) {
  console.log('function executed for item: ' + item);
}

$.each(items, function (index, item) {
  var timeoutValue = index * 2000;
  setTimeout(function() {
    console.log('waited ' + timeoutValue + ' milliseconds');
    functionToExecute(item);
  }, timeoutValue);
});

Result:

waited 0 milliseconds
function executed for item: item1
waited 2000 milliseconds
function executed for item: item2
waited 4000 milliseconds
function executed for item: item3 

Does it mean that I'm blocking reading any input from the Server/Client for this socket for 2000 millisecond and after this time the socket is ready to read data?

No, it means that if no data arrives within 2000ms a SocketTimeoutException will be thrown.

What does it mean timeout expire?

It means the 2000ms (in your case) elapses without any data arriving.

What is the option which must be enabled prior to blocking operation?

There isn't one that 'must be' enabled. If you mean 'may be enabled', this is one of them.

Infinite Timeout menas that the socket does't read anymore?

What a strange suggestion. It means that if no data ever arrives you will block in the read forever.

For XAMPP users you can use this:

# Use XAMPP version of PHP
export PATH=/Applications/XAMPP/xamppfiles/bin:$PATH
source ~/.bash_profile

And you can check it with:

php -v

Kyle's answer is pretty good. I think the only additional clarification is that the closure is basically a snapshot of the stack at the point that the lambda function is created. Then when the function is re-executed the stack is restored to that state before executing the function. Thus as Kyle mentions, that hidden value (count) is available when the lambda function executes.

I know this is an old question but on Windows, this filters the git output to the files and changed line numbers:

(git diff -p --stat) | findstr "@@ --git"

diff --git a/dir1/dir2/file.cpp b/dir1/dir2/file.cpp
@@ -47,6 +47,7 @@ <some function name>
@@ -97,7 +98,7 @@ <another functon name>

To extract the files and the changed lines from that is a bit more work:

for /f "tokens=3,4* delims=-+ " %f in ('^(git diff -p --stat .^) ^| findstr ^"@@ --git^"') do @echo %f

A common cause is cloning using the default (HTTPS) instead of SSH. You can correct this by going to your repository, clicking "Clone or download", then clicking the "Use SSH" button above the URL field and updating the URL of your origin remote like this:

git remote set-url origin [email protected]:username/repo.git

This is documented at GitHub: Switching remote URLs from HTTPS to SSH.

Had the same problem a few minutes ago, I was missing the 'Maven depencendies' library in my Deployment Assembly. I added it through the section 'Web Deployment Assembly' in Eclipse

This should work:

date +%s

The top answers here work, but I found something more elegant in Michael Hampton's answer to a related question. The "new" (firewalld-0.3.9-11+) --runtime-to-permanent option to firewall-cmd lets you create runtime rules and test them out before making them permanent:

$ firewall-cmd --zone=<zone> --add-port=2888/tcp
<Test it out>
$ firewall-cmd --runtime-to-permanent

Or to revert the runtime-only changes:

$ firewall-cmd --reload

Also see Antony Nguyen's comment. Apparently firewall-cmd --reload may not work properly in some cases where rules have been removed. In that case, he suggests restarting the firewalld service:

$ systemctl restart firewalld

I had the same problem but was because I had already previously installed xampp , and I tried to install a newer version , then I installed the newer version in another file directory (I named the file directory xampp2). I solved the problem after uninstall the newer version, rename the old one (I renamed as xamppold), and installing xampp again.

I guess if you didn't installed xampp in another file directory or something like that , it should be enough to reinstall xampp. If you are worried about your files , you always can make a backup before reinstalling xampp.

I solved the problem after watching the xampp activity log (the list of the bottom) and realizing xampp was trying to open the custom file path but I had another route path. If the first option didn't worked, at least you can scroll up in the activity log and see whats the error you get while starting as admin and trying to re install the Apache module or trying to start the module.

You may wander why I didn't just simply uninstall the whole thing from the beginning , and the answer would be I have tweak a couple of things of xampp for some different projects (from changing the ports , to add .dll to run mongo.db in Apache), and I'm just too lazy to re-do everything again :b

I hope my answer can be helpful for anyone since is my first time writing in stackoverflow :)

Cheers

filepath.Abs("./")

Abs returns an absolute representation of path. If the path is not absolute it will be joined with the current working directory to turn it into an absolute path.

As stated in the comment, this returns the directory which is currently active.

After scouring this thread and playing around with all the options above - I settled with a Singleton that can be created with proper constructors:

export default class Singleton {
  private static _instance: Singleton

  public static get instance(): Singleton {
    return Singleton._instance
  }

  constructor(...args: string[]) {
    // Initial setup

    Singleton._instance = this
  }

  work() { /* example */ }

}

It would require an initial setup (in main.ts, or index.ts), which can easily be implemented by
new Singleton(/* PARAMS */)

Then, anywhere in your code, just call Singleton.instnace; in this case, to get work done, I would call Singleton.instance.work()

A variation of DixonD's excellent answer (above).

Ok, find color in HSV space is an old but common question. I made a hsv-colormap to fast look up special color. Here it is:

The x-axis represents Hue in [0,180), the y-axis1 represents Saturation in [0,255], the y-axis2 represents S = 255, while keep V = 255.

To find a color, usually just look up for the range of H and S, and set v in range(20, 255).

To find the orange color, we look up for the map, and find the best range: H :[10, 25], S: [100, 255], and V: [20, 255]. So the mask is cv2.inRange(hsv,(10, 100, 20), (25, 255, 255) )

Then we use the found range to look for the orange color, this is the result:

The method is simple but common to use:

#!/usr/bin/python3
# 2018.01.21 20:46:41 CST
import cv2

img = cv2.imread("test.jpg")
hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)
mask = cv2.inRange(hsv,(10, 100, 20), (25, 255, 255) )
cv2.imshow("orange", mask);cv2.waitKey();cv2.destroyAllWindows()

I got this error after change a loop in my program, let`s see:

for ...
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:

for ...
  x_batch = []
  y_batch = []
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

Then, check if you are using np.asarray() or something like that.

Pecl PDO package is now deprecated. By the way the debian package php5-pgsql now includes both the regular and the PDO driver, so just:

apt-get install php-pgsql

Apache also needs to be restarted before sites can use it:

sudo systemctl restart apache2

Quick answer: replace it.

In the code below I use the replaceWith jQuery method to replace the control with a clone of itself. In the event you have any handlers bound to events on this control, we'll want to preserve those as well. To do this we pass in true as the first parameter of the clone method.

<input type="file" id="control"/>
<button id="clear">Clear</button>

var control = $("#control");

$("#clear").on("click", function () {
    control.replaceWith( control = control.clone( true ) );
});

Fiddle: http://jsfiddle.net/jonathansampson/dAQVM/

If cloning, while preserving event handlers, presents any issues you could consider using event delegation to handle clicks on this control from a parent element:

$("form").on("focus", "#control", doStuff);

This prevents the need for any handlers to be cloned along with the element when the control is being refreshed.

You can display an image in your own window using Tkinter, w/o depending on image viewers installed in your system:

import Tkinter as tk
from PIL import Image, ImageTk  # Place this at the end (to avoid any conflicts/errors)

window = tk.Tk()
#window.geometry("500x500") # (optional)    
imagefile = {path_to_your_image_file}
img = ImageTk.PhotoImage(Image.open(imagefile))
lbl = tk.Label(window, image = img).pack()
window.mainloop()

For Python 3, replace import Tkinter as tk with import tkinter as tk.

The best way to enable the production mode for an Angular 2 application, is to use angular-cli and build the application with ng build --prod. This will build the application with production profile. Using angular-cli has the benefit of being able to use development mode using ng serve or ng build while developing without altering the code all the time.

try this

provider = new CultureInfo("en-US");
DateTime.ParseExact("9/1/2009", "M/d/yyyy", provider);

Bye.

You can't use it in the way you describe. The point about generic types, is that although you may not know them at "coding time", the compiler needs to be able to resolve them at compile time. Why? Because under the hood, the compiler will go away and create a new type (sometimes called a closed generic type) for each different usage of the "open" generic type.

In other words, after compilation,

DoesEntityExist<int>

is a different type to

DoesEntityExist<string>

This is how the compiler is able to enfore compile-time type safety.

For the scenario you describe, you should pass the type as an argument that can be examined at run time.

The other option, as mentioned in other answers, is that of using reflection to create the closed type from the open type, although this is probably recommended in anything other than extreme niche scenarios I'd say.

If you have Jackson integeration with your application to serialize your bean to JSON format, then you can use Jackson anotation @JsonFormat to format your date to specified format.
In your case if you need your date into yyyy-MM-dd format you need to specify @JsonFormat above your field on which you want to apply this format.

For Example :

public class Subject {

     private String uid;
     private String number;
     private String initials;

     @JsonFormat(pattern="yyyy-MM-dd")
     private Date dateOfBirth;  

     //Other Code  

}  

From Docs :

annotation used for configuring details of how values of properties are to be serialized.

Yes, you have to get all records, update them and then call SaveChanges.

You can use the eq method or selector:

$('ul').find('li').eq(index).css({'background-color':'#343434'});

Following the exceedingly simple method from Andralor here fixed the issue for me: https://github.com/fancyapps/fancyBox/issues/766

Essentially, call the iframe again onUpdate:

$('a.js-fancybox-iframe').fancybox({
    type: 'iframe',
    scrolling : 'visible',
    autoHeight: true,
    onUpdate: function(){
     $("iframe.fancybox-iframe");
   }
 });

Good answers so far, I want to only add that you could check the type of a node using nodeType:

Use make_response of Flask something like

@app.route("/")
def home():
    resp = make_response("hello") #here you could use make_response(render_template(...)) too
    resp.headers['Access-Control-Allow-Origin'] = '*'
    return resp

From flask docs,

flask.make_response(*args)

Sometimes it is necessary to set additional headers in a view. Because views do not have to return response objects but can return a value that is converted into a response object by Flask itself, it becomes tricky to add headers to it. This function can be called instead of using a return and you will get a response object which you can use to attach headers.

pgrep can get you all of the child PIDs of a parent process. As mentioned earlier $$ is the current scripts PID. So, if you want a script that cleans up after itself, this should do the trick:

trap 'kill $( pgrep -P $$ | tr "\n" " " )' SIGINT SIGTERM EXIT

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

unanswered core problem persists:

My working directory is now c:\users\projectname.git So then I try to import the project using the eclipse "import" option. When I try to import selecting the option "Use the new projects wizard" the source code is not imported, if I import selecting the option "Import as general project" the source code is imported but the created project created by Eclipse is not a java project. When selecting the option "Use the new projects wizard" and creating a new java project using the wizard should'nt the code be automatically imported ?

Yes it should.

It's a bug. Reported here.

Here is a workaround:

• Import as general project

• Notice the imported data is no valid Eclipse project (no build path available)

• Open the .project xml file in the project folder in Eclipse. If you can't see this file, see How can I get Eclipse to show .* files?.

• Go to source tab

• Search for <natures></natures> and change it to <natures><nature>org.eclipse.jdt.core.javanature</nature></natures> and save the file

  (idea comes from here)

• Right click the src folder, go to Build Path... and click Use as Source Folder

After that, you should be able to run & debug the project, and also use team actions via right-click in the package explorer.

If you still have troubles running the project (something like "main class not found"), make sure the <buildSpec> inside the .project file is set (as described here):

<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>

As others have explained, var self = this; allows code in a closure to refer back to the parent scope.

However, it's now 2018 and ES6 is widely supported by all major web browsers. The var self = this; idiom isn't quite as essential as it once was.

It's now possible to avoid var self = this; through the use of arrow functions.

In instances where we would have used var self = this:

function test() {
    var self = this;
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", function() {
        console.log(self.hello); // logs "world"
    });
};

We can now use an arrow function without var self = this:

function test() {
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", () => {
        console.log(this.hello); // logs "world"
    });
};

Arrow functions do not have their own this and simply assume the enclosing scope.

SELECT datname FROM pg_database WHERE datistemplate = false

#for postgres

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

I had a similar problem with HttpClient version 4.

I couldn't connect to the server because of a SOCKS proxy error and I fixed it using the below configuration:
